Will Young's dream collaboration would be with Icelandic shouting expert Björk.
When 'quizzed' by Virgin Red Room on who he would love to work with, Will remarked that the answer "changes on a daily basis", before settling resolutely on the arty swanfrock botherer.
"It's kind of always been Björk really," he remarked. "Big singer, big tracks, pretty amazing."
Another popstar Will thinks is similarly amazing is "friend of mine" Sia, whose David Guetta collaboration is Will's favourite marathon-running track.
